Franz Kahn has made many original contributions to plasma astrophysics, cosmical gas dynamics and the physics of star formation, with significant early papers on the structure of ionisation fronts and collision-free shocks. More recently he has done important work on stellar winds and galactic fountains, on planetary nebulae and on remnants of novae and supernovae. His versatility is shown by papers on the spiral structure of the Galaxy, on the nature of the Local Group and the account (with the late Carla Kahn) of the Einstein-de Sitter correspondence.[11] Kahn's style is especially noteworthy for his skill in building simple mathematical models which bring out the essence of the physics.[12]
Kahn married Carla Copeland (Carla Kahn) in 1951[4] and had four children.[9] Kahn died of a heart attack in Bourne End, Buckinghamshire, on 8 February 1998 and was buried in the Jewish cemetery in south Manchester.[13] He was survived by his four children.[13][14]
